Solution

The correct option is D $D a t a i n s u f f c i e n t$
The resistance of a given resistor depends upon the type of material i.e. its resistivity, which is a function of temperature. What else does it depend upon?
Yes right, its length and area of cross section.
Hence we cannot comment on resistivity until it is provided that the resistors are of similar shape and size. Hence D.
